对于亮晶晶好友判定规则
刚看了两则 N 社的回复[1][2]后整理一下：
```
var 亮晶晶好友机率 = 2% // (数字乱写，参考就好)
if (!四心好友) { 滚; }
if (该友 === 蓝圈) { 滚; }
if (好友清单中尚无蓝圈) { 亮晶晶好友机率 += 1% }
if (random(0, 1) < 亮晶晶好友机率) {
欧咩爹都~

```
好吧，用白话文整理成三点： XD
* 好友蓝圈一天只有第一次互动才会赋与（已知，旧有规则）
* 亮晶晶好友只有在四心好友上蓝圈时，佛系判定 (机缘不够，回头是岸)
* 训练师好友清单中的第一个蓝圈，亮晶晶好友机率略高些（首杀加成）

Happy to clarify, Trainer. The chances of becoming Lucky with your Best
Friends are random. The possibilities are comparatively higher on your first
interaction of the day. However, you can still turn Lucky on your subsequent
interactions. Hope the odds are in your favor! ^SP

To clarify, only the first interaction you have with your Best Friend per day
could make you Lucky Friends, replacing increased Friendship levels. So, if
you and a Best Friend trade and later participate in a Raid on the same day,
only the trade could make you Lucky Friends. ^MM
